A/C

65 to 70 is normal, if it's still ambient temperature coming out of the vents, see if compressor clutch is engaging, your AC system may be low on gas

Thank you !

You should hear the compressor clucth clicking and hear a change in the sound of the engine and idle when the A/C clutch engages and disengages turning the compressor on and off as it cycles. If you can't hear that or see the very end of the compressor spinning and stopping your clutch or one of the pressure sensors that turn it on and off could be bad, or it may need a can of booster because the gas pressure is low.
